1 dendron, Transmits impulses between neurones and have many axons and dendrons, Transmit impulses from relay or sensory neurones to an effector and have one long axon and many short dendrons, Membrane rich in lipid surrounding axons of some neurones speeding up impulse transmission, Specialised cells with up to 20 layers of double phospholipid bilayer, Gap of 2-3micrometere between the schwann cells, Autoimmune disease effecting 100,000 people in the UK as a neurological condition where the myelin sheath breaks down, muscle or gland that carries out a response from a stimulus, Receptor for pressure and movement for example the pacinian corpuscle in the skin, Receptor for chemical stimuli for example the olfactory receptor in the nose, Receptor for heat for example the end-bulbs of Krause in the tongue, Receptor for light for example cone ells in the eyes, Converts stimulus into a nerve impulse called a generator potential, specific sensory receptor that detects mechanical pressure, Channels that stretch when pressure is exerted and change permeability to sodium, The potential difference across the membrane of a axon of a neurone at rest (-60mV) the membrane is polarised, The change in potential difference across the neurone membrane of an axon when stimulated (-40mV) the membrane is depolarised, A change in potential difference from negative to positive across the membrane of a neurone, A change in potential difference from positive to negative across the membrane of a neurone, channels that open or close as a result of a change in potential difference across a membrane, a change or event that leads to a cascade of similar events, A large amount of potassium ions diffuse into the membrane and over polarise the membrane, A time when the axon can't be excited between action potentials all sodium channels are closed to prevent overlaps in action potentials and maintains the unidirectional movement, The formation of localised currents around and schwann cell and the jumping of action potential between nodes of Ranvier, Action potentials are all the same size no matter the strength of the stimulus if the threshold is reached a action potential will be released stronger stimuli release more frequent action potentials, The junction or small gap between 2 neurones or a neurone and an effector, The 20-30micrometer gap between the axon of the presynaptic neurone and the dendrite of post synaptic neurone, Synapses commonly in the CNS and uses the neurotransmitter acetylcholine, swollen part of the presynaptic neurone which contains many mitochondria and ER to manufacture neurotransmitters, Vesicles containing neurotransmitters and fuse with the presynaptic membrane and release their contents into synaptic cleft, Molecules which the neurotransmitters bind to the postsynaptic membrane, Result in the depolarisation of the post synaptic neurone and can trigger an action potential (Acetylcholine), Result in the hyperpolarisation of the post synaptic membrane preventing the transmission of an action potential (GABA), A build up of neurotransmitters in a synapse to the threshold value needed to trigger an action potential, Many presynaptic neurones connect to one post synaptic neurone, A single presynaptic neurone releases neurotransmitters over a short period of time in order to trigger an action potential, All of the neurones that connect the CNS to the rest of the body, Under conscious control and carries out voluntary actions, Under subconscious control and is working constantly and for involuntary actions, provides the fight or flight response and has the neurotransmitter noradrenaline, Provides the relaxing response and has the neurotransmitter acetylcholine, Controls voluntary actions such as learning, memory, personality and conscious thought and is the largest part of the brain at the top, Controls unconscious functions such as posture, balance and non-voluntary movement is the cauliflower looking part at the back, Part of the brain used in autonomic control for example heart and breathing rates, Regulatory center of temperature and water balance, Stores and releases hormones that regulate many body functions, front section of a pituitary gland and produces 6 hormones including FSH, Stores and releases hormones produced by the hypothalamus including ADH, The fast involuntary response to a stimulus preventing or minimizing the negative effect on the body when confronted with danger, A column of nervous tissue running up the back surrounded by the spine for protection, Spinal reflex test used by doctors to check for nervous problems, Involuntary blinking of the eyelid to protect the eye when the cornea is stimulated by a possibly dangerous stimulus, A reflex that occurs in the brain not the spinal cord, Most common muscle in the body is striated and is used voluntarily for movement, Myogenic muscles in the heart and involuntary contract to cause the heart to beat in a regular rhythm, Involuntary non-striated muscle cells with a slow contraction speed often used in transport of substances around the body, Long cylindrical organelles found in muscles, made of proteins and are specialised for contractions, Protein made of 2 stands twisted around each other and make up the thinner filament of a myofibril, A long rod shaped fibre with bulbons heads that project to one side and make up the thicker filament of a myofibril, Region were actin and myosin filaments do not overlap. The electrical impulses that pass along neurones is due to movement of ions across membranes. Detailed mark scheme is included. 10:00. Essential Environment: The Science Behind the Stories Jay H.
